I'm not going to say too much about this game, as I don't really care enough about the game to go into the gameplay. Martin sent me a prototype of the game, but there isn't much to say about it. Doing a file compare with NSRT:

As you can see, there are only four bytes that differ. These addresses correspond to the forward and reverse checksum checks in the internal header. My theory is they sent out the prototype with a bad checksum to discourage distributing it on BBS sites.

The prototype came in a US-style cart with a generic Nintendo label. The date on the label is August 1992. The game itself was released in October 1992.
